Antidiuretic hormone (ADH): A relatively small (peptide) molecule that is released by the pituitary gland at the base of the brain after being made nearby (in the hypothalamus).ADH has an antidiuretic action that prevents the production of dilute urine (and so is antidiuretic). syndrome of inappropriate secretion of ADH results in the inability to put out dilute urine, perturbs fluid (and electrolyte) balance, and causes nausea, vomiting, muscle cramps, confusion and convulsions.
It is secreted by the adrenal cortex  (adrenal glands). Antidiuretic hormone is a peptide hormone and is  made by the hypothalamus gland it regulates the body's retention of  water.A decrease is blood pressure triggers the release of the  hormone from the posterior pituitary gland.he 3 hormones that are produced to regulate urine are Aldosterone,  AHD (antidiuretic hormone), and ANH (atrial natriuretic hormone).
